Planarians belong to the superphylum Lophotrochozoa, phylum Platyhelminthes, subphylum Catenulidea, class Rhabditophora (some consider the artificial grouping Turbellaria), order Tricladida, suborder Paludicola, and families Dugesiidae, Kenkiidae, Planariidae, and :// Planarian, any of a group of widely distributed, mostly free-living flatworms of the class Turbellaria (phylum Platyhelminthes).

Turbellarians are nearly all free-living (nonparasitic) and most are marine. Planarians, members of the genus Dugesia, are carnivores or scavengers in unpolluted ponds and streams.
